(As with the pertinent sections of Shrevc, Book Company (1945 can be admixed with the above supra, the tables of that patent are incorporated hereinacetate. above as fully set forth.)

When perfuming materials containing water, it may be desirable to employ the compound of Formula I (or perfume composition containing same) with a buffering agent which will tend to keep the material to be scented at a pH between 6 and 8.

It is immediately apparent to a skilled practitioner that other materials than those set forth above can be perfumed according to this invention. For example, mothballs, soaps and synthetic detergents, whether liquids, solids, powders, laundry, medicinal soaps, or toilet bars can be perfumed.

This invention can be extended to the preparation of perfumes and perfume products prepared from a mixture of highly branched octyl acetates which are produced by the acid catalyzed reaction between di-isobutylene (2,4,4- trimethyl pentene-Z) and acetic acid. In most instances, the predominant product in the mixture of esters produced by this reaction is the compound of Formula I.

In summary, a preferred embodiment of this invention is a perfumed composition comprising (1) as a perfuming agent, an odoriferous amount of 2,2,4-trimethyl-2- pentyl acetate and (2) as a carrier therefor, a non-drying inert oleaginous substance having for each 100 parts by weight of said oleaginous substance from about 5 to about 30 parts of an alcohol having from 16 to about 30 carbon atoms. The oleaginous substance called for in this embodiment are materials such as lanolin, paraffin wax, Petrolatum, mineral oil, white beeswax, Carbowax 4000, Carbowax 400, and hydrogenated cottonseed oil. The alcohols described in this embodiment are exemplified by cetyl alcohol, stearyl alcohol, cholesterol, lanolin alcohols, and the like. These materials and their use thereof are illustrated by Bases 1-13 defined hereinabove.

What we claim is:

1. A perfumed composition comprising (1) as a perfuming agent, an odoriferous amount of 2,4,4-trimethyl- Z-pentyl acetate, and (2) as a carrier therefor, a nondrying inert oleaginous substance having for each 100 parts by weight of said oleaginous substance from about 5 to about parts of an alcohol having from 16 to about 30 carbon atoms.
